ASTM D5832-98

Standard Test Method for Volatile Matter Content of Activated Carbon Samples

SCOPE
1.1 This test method determines the percentage of gaseous products, exclusive of moisture vapor, present in virgin and used activated carbons which are released under specific conditions of the test.  
1.2 The following safety caveat applies to the procedure section of this test method: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
